Issue Details

I'm trying to run a project on a NI RIO target (CompactRIO, sbRIO, myRIO), but the status light on my target device is blinking and I'm seeing the following error:

Error -63044 occured at an unidentified location

Possible reason(s):
The RIO server could not be found on the specified remote device. Ensure that NI-RIO software is installed and that the RIO server is running and properly configured.

For NI-RIO 2.3 and later, refer to Software>>NI-RIO Settings under the system in MAX. Prior to NI-RIO 2.3, refer to Software>>NI-VISA>>VISA Options under the system in MAX.

The error is also shown in the following image:


This error is preventing me from being able to work with my device. How do I resolve this error?

Solution

Note: The status light should be lit on your RIO target during the power up state, then turn off for normal operation.

If the Status LED is blinking, the RIO is in a state that cannot run code successfully. There are multiple errors that could occur that are characterized by the number of times the status light blinks in a row. Try the troubleshooting steps below:
  • Check the User Guide or Specifications Sheet for your specific device for additional information on what the blinking Status LED is indicating. You can find the user guide or specifications sheet for your device by following the steps below:
    1. Enter <your specific device> in the search bar of the Product Manuals search page to locate the device's documentation.
    2. Once you have found the device's User Guide or Specifications Sheet, search for Status LED within the document. This will allow you to find the Status LED Indications section that provides information on what the flashing LED indicates along with some troubleshooting steps to try.
  • If the status light is constantly flashing or solid for more than a few seconds, contact National Instruments support.
  • Try resetting and reinstalling software to your real-time target 
  • Try reinstalling the RIO or myRIO drivers in the machine.
